There is provided a radio device housing, without the risk of causing deterioration of the mechanical strength and the rigidity of the housing with respect to bend or twist deriving from a small size and a thin shape of the radio device main body. First ribs are provided in either an upper case or a lower case on the entire periphery along the joint surface of the upper case and the lower case. A plurality of fitting nails are provided in either the upper case or the lower case for holding and fixing with each other. Second ribs are provided in the rifts in the case not having the first ribs. Third ribs are provided on the fitting nails and the second ribs for contacting the upper case and the lower case when they are fitted with each other so that they are not displaced in the thrust direction with each other.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A radio device housing comprising: an upper case; a lower case; a plurality of first ribs distributed at a periphery along an interior of a joint surface of one of said upper case and said lower case; a plurality of fitting parts provided on the other of said upper case and said lower case, wherein said fitting parts define a receptacle; a plurality of second ribs distributed among said plurality of fitting parts; a plurality of third ribs provided on said upper case and said lower case; and a plurality of fitting nails provided on the one of said upper case and said lower case which includes said first ribs, said fitting nails including a projecting engaging part that fits within said receptacle defined by said fitting parts, wherein each instance of said fitting nails is nested between a pair of said third ribs, and further wherein said first ribs substantially occupy that portion of the periphery not occupied by any of said third ribs and said fitting nails, and still further wherein each instance of said second ribs is connected to an instance of said third ribs on the one of the upper and lower case which includes said first ribs.
2. The radio device housing according to claim 1 , wherein an instance of said third ribs on said upper case are in contact with an instance of said third ribs on said lower case at two or more points when said housing is assembled.
3. The radio housing according to claim 1 , wherein a surface on said third ribs has an inclination.
4. The radio device housing according to claim 1 , further comprising: said receptacle of said fitting parts comprising ribs, wherein when the case is assembled, said engaging part of said fitting nails engages with said receptacle of said fitting parts such that said ribs of said receptacle are on two sides of said engaging part.
5. The radio device housing according to claim 1 , wherein each instance of said fitting nails on said upper case is connectively associated with an instance of said third ribs on said upper case; and further wherein each instance of said third ribs on said lower case is connectively associated with an instance of said second ribs on said lower case.
6. A portable radio device comprising: a radio device housing comprising: an uppercase; a lower case; a plurality of first ribs distributed at a periphery along an interior of a joint surface of one of said upper case and said lower case; a plurality of fitting parts provided on the other of said upper case and said lower case, wherein said fitting parts define a receptacle; a plurality of second ribs distributed among said plurality of fitting parts; a plurality of third ribs provided on said upper case and said lower case; and a plurality of fitting nails provided on the one of said upper case and said lower case which includes said first ribs, said fitting nails including a projecting engaging part that fits within said receptacle defined by said fitting parts, wherein each instance of said fitting nails is nested between a pair of said third ribs, and further wherein said first ribs substantially occupy that portion of the periphery not occupied by any of said third ribs and said fitting nails, and still further wherein each instance of said second ribs is connected to an instance of said third ribs on the one of the upper and lower case which includes said first ribs.
7. A radio device housing comprising: an upper case having a peripheral edge; a lower case having a peripheral edge; a plurality of first ribs distributed at the peripheral edge along a joint surface of one of said upper case and said lower case; a plurality of fitting parts provided on the other of said upper case and said lower case; a plurality of second ribs distributed among the plurality of said fitting parts and having a portion protruding beyond said peripheral edge; a plurality of third ribs provided on said upper case and said lower case; and a plurality of fitting nails provided on one of said upper case and said lower case, wherein each instance of said fitting nails is connectively associated with an instance of said third ribs, and further wherein said first ribs substantially occupy that portion of the periphery not occupied by any of said third ribs and said fitting nails, and still further wherein each instance of said second ribs is connectively associated with an instance of said third ribs.
8. A radio device housing comprising: an upper case; a lower case; a plurality of first ribs distributed across a periphery along a joint surface of one of said upper case and said lower case; a plurality of fitting parts provided on the other of said upper case and said lower case, said fitting parts including engaging ribs; a plurality of second ribs distributed among the plurality of said fitting parts; a plurality of third ribs provided on said upper case and said lower case; and a plurality of fitting nails provided on one of said upper case and said lower case, said fitting nails including an engaging part, wherein each instance of said fitting nails is connectively associated with an instance of said third ribs, and further wherein said first ribs substantially occupy that portion of the periphery not occupied by any of said third ribs and said fitting nails, and still further wherein each instance of said second ribs is connectively associated with an instance of said third ribs, and even further wherein, when the case is assembled, said engaging part of said fitting nails engage with said fitting parts such that said engaging ribs are on two sides of said engaging part.
